在按照老师3-36 Uwsgi反向代理模式 视频中的步骤里，执行pip3 install django 命令时，报如下错误:
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by ‘ReadTimeoutError(“HTTPSConnectionPool(host=‘pypi.org’, port=443): Read timed out. (read timeout=15)”,)’: /simple/django/

Could not find a version that satisfies the requirement django (from versions: )
